    B. The cell cycle
    Explanation
    The process of cells growing and dividing is known as the cell cycle. This is a continuous process that includes various stages such as interphase, mitosis, and cytokinesis. During interphase, the cell grows and prepares for division. Mitosis is the stage where the cell's nucleus divides into two identical nuclei, and cytokinesis is the division of the cytoplasm to form two new cells. Overall, the cell cycle is a fundamental process that ensures the growth, development, and reproduction of cells in living organisms.

      Metaphase

    Correct Answer
    A. Interphase
    Explanation
    Interphase is the first major part of the cell cycle. It is a period of cell growth and preparation before cell division occurs. During interphase, the cell undergoes three phases: G1 phase, S phase, and G2 phase. In the G1 phase, the cell grows and carries out its normal functions. In the S phase, DNA replication takes place, ensuring that each daughter cell will have a complete set of genetic material. Finally, in the G2 phase, the cell continues to grow and prepares for cell division. Therefore, interphase is the correct answer as it encompasses the initial stages of the cell cycle.

    • D.

      G1, S phase, G2

    Correct Answer
    D. G1, S phase, G2
    Explanation
    The correct answer is G1, S phase, G2. Interphase is the longest phase of the cell cycle and consists of three stages: G1 (gap 1), S phase (synthesis), and G2 (gap 2). During G1, the cell grows and carries out its normal functions. In S phase, DNA replication occurs, resulting in the duplication of the cell's genetic material. G2 is a period of preparation for cell division, where the cell continues to grow and synthesize proteins necessary for mitosis.

    During what does the cell rapidly grow and have it's organelles copied? 

    Correct Answer
    G1
    gap 1
    Explanation
    During the G1 phase or gap 1 phase of the cell cycle, the cell undergoes rapid growth and prepares for DNA replication. This is the phase where the cell accumulates energy and nutrients, increases in size, and duplicates its organelles in preparation for cell division. Therefore, the correct answer is G1 or gap 1.

    Rate this question:

  • 5. 

    During what does the DNA replicate itself?

    Correct Answer
    S phase
    synthesis phase
    Explanation
    During the S phase or synthesis phase of the cell cycle, DNA replicates itself. This is the phase where the cell prepares for cell division by duplicating its genetic material. DNA replication occurs during this phase to ensure that each daughter cell receives an identical copy of the DNA. The synthesis phase is a crucial step in cell division and is responsible for the accurate transmission of genetic information from one generation to the next.

    Rate this question:

  • 6. 

    During what are more organelles made and the cell prepares to divide?

    Correct Answer
    G2
    gap2
    Explanation
    During the G2 phase, more organelles are made and the cell prepares to divide. This phase follows the S phase where DNA replication occurs. In G2, the cell undergoes further growth and prepares for cell division by synthesizing proteins and organelles needed for the upcoming division. The gap2 (gap phase 2) refers to the period of time between the completion of DNA replication in S phase and the onset of cell division in M phase. Therefore, both G2 and gap2 are correct answers as they represent the same phase of the cell cycle.

    What are the two big parts of the the 2nd phase of the cell cycle, M-phase? 

    Correct Answer
    mitosis and cytokinesis
    Explanation
    The second phase of the cell cycle, M-phase, consists of two major processes: mitosis and cytokinesis. Mitosis is the division of the cell's nucleus, where the replicated chromosomes are separated into two identical sets and distributed to two daughter cells. Cytokinesis, on the other hand, is the division of the cytoplasm, which completes the cell division process by forming two separate daughter cells. Therefore, both mitosis and cytokinesis are essential components of the M-phase, ensuring the accurate distribution of genetic material and the formation of two new cells.

  • 8. 

    What is separating genetic material into 2 nuclei known as?

    Correct Answer
    mitosis
    Explanation
    Mitosis is the process of cell division that results in the formation of two genetically identical nuclei. During mitosis, the genetic material, which includes chromosomes, is evenly distributed between the two newly formed nuclei. This ensures that each daughter cell receives the same amount of genetic material as the parent cell. Therefore, the process of separating genetic material into two nuclei is known as mitosis.

  • 9. 

    What is the process that divides the cytoplasm known as?

    Correct Answer
    cytokinesis
    Explanation
    Cytokinesis is the process by which the cytoplasm of a cell is divided into two daughter cells after cell division. During cytokinesis, the cytoplasmic contents, including organelles and cytosol, are separated and distributed equally between the two daughter cells. This process ensures that each daughter cell receives the necessary cellular components to function independently. Cytokinesis is a crucial step in cell division and is essential for the growth and development of multicellular organisms.

    What are the 4 phases of mitosis?

    Correct Answer
    prophase, metaphase, anaphase, telophase
    Explanation
    The 4 phases of mitosis are prophase, metaphase, anaphase, and telophase. In prophase, the chromosomes condense and become visible, the nuclear envelope breaks down, and the spindle fibers form. During metaphase, the chromosomes align at the center of the cell. In anaphase, the sister chromatids separate and move towards opposite poles of the cell. Finally, in telophase, the chromosomes reach the poles, the nuclear envelope reforms, and the spindle fibers disassemble. These phases ensure the accurate division of genetic material into two daughter cells.

    Rate this question:

  • 11. 

    In what phase do the following things happen? This is the longest phase in mitosis-chromatin condenses into chromosomes -nuclear envelope disappears-nucleolus disappears-spindle fibers form

    Correct Answer
    prophase
    Explanation
    During prophase, the chromatin condenses into visible chromosomes, the nuclear envelope disappears, the nucleolus disappears, and spindle fibers form. This is the longest phase in mitosis because it involves multiple crucial events that prepare the cell for division. The condensation of chromatin into chromosomes ensures that the genetic material is organized and ready for separation. The disappearance of the nuclear envelope and nucleolus allows for the spindle fibers to interact with the chromosomes. The formation of spindle fibers is essential for the movement and alignment of chromosomes during later stages of mitosis.

    Rate this question:

  • 12. 

    In which of the phases of mitosis do:-chromosomes line up along the equator of the cell -the spindle fibers connect to chromosome @ the centromere

    Correct Answer
    metaphase
    Explanation
    During metaphase, the chromosomes line up along the equator of the cell, forming a single line called the metaphase plate. At this stage, the spindle fibers, which are microtubules, connect to the chromosomes at their centromeres. This alignment and attachment of the spindle fibers allow for the equal separation of genetic material during the subsequent phase of mitosis, anaphase. Therefore, metaphase is the correct phase of mitosis where both of these events occur.

    Rate this question:

  • 13. 

    What phase in mitosis does the following:-the spindle fibers pulll the chromosomes apart-each identical chromatide moves to separate poles of the cell

    Correct Answer
    anaphase
    Explanation
    During anaphase in mitosis, the spindle fibers contract and pull the sister chromatids apart. Each identical chromatid moves towards opposite poles of the cell, ensuring that each new cell formed will receive a complete set of chromosomes. This phase is crucial for the proper distribution of genetic material and the formation of two genetically identical daughter cells.

    Rate this question:

  • 14. 

    What phase of mitosis does the following:-nuclear envelope reforms-nucleolus reappears-chromosomes uncoil-cleavage begins to form

    Correct Answer
    telophase
    Explanation
    Telophase is the correct answer because it is the final phase of mitosis. During telophase, the nuclear envelope reforms around the separated chromosomes, the nucleolus reappears in the newly formed nuclei, and the chromosomes begin to uncoil and return to their extended form. Additionally, cleavage, which is the process of cell division, begins to form during telophase. Therefore, all the mentioned characteristics align with the events that occur in telophase.

    Rate this question:

  • 15. 

    In what process does the following happen?the cleavage continuesand splits the cell into 2 genetically identical cells. Final cells referred to as daughter cells.

    Correct Answer
    cytokinesis
    Explanation
    Cytokinesis is the process in which the cytoplasm of a cell divides, resulting in the formation of two daughter cells. During cytokinesis, the cleavage furrow forms and continues to deepen, eventually splitting the cell into two genetically identical daughter cells. These daughter cells are the final result of the cell division process and are referred to as daughter cells.
